Sub Swapper

Learn languages the easy way.

Sub Swapper is a Python script designed to swap a specified percentage of subtitles between two subtitle files. It also takes into account a specified grade level to intelligently guess whether the viewer would likely understand each sentence.

The script is designed to enhance language learning by making it easier and more enjoyable to practice new languages. The recommended usage is to watch TV series or films dubbed in the target language you want to learn, with subtitles comprising 80% in your native language and 20% in the language of the dub.

Features

• Swap a percentage of subtitles between two subtitle files.
• Set a specific grade reading level to ensure you will understand the subtitles.
• Specify input and output paths for subtitle files.

Usage

Command-line Arguments

• -p: Specify the percentage of subtitles to be swapped.
• -o: Specify the output path for the swapped subtitles.
• -g: Specify the grade level for reading comprehension.
• -i: Specify two paths for input subtitle files.

Example

python3 -m subs_swapper.main -i 'subs_english.srt' 'subs_espanish.srt' -p 20 -g 3 -o output.srt

This command will swap 20% of subtitles between subs_english.srt and subs_spanish.srt, considering a grade level of 3, and save the result in output.srt.

Running Tests

To run the tests, use the following command:

python3 -m tests.test_compare_subs

Limitations

• Both subtitles need to be synchronized
• Remember that expressions and idioms might affect understanding, even though they may appear to have a low grading level
